1 Claim. (Cl. 4-292) This invention pertains to a waste outlet crossbar and more particularly it is concerned with a novel type of crossbar in which there is a certain degree of resilience to aid in inserting and removing the crossbar member as well as to maintain it snugly in position during the course of actual service.

In order to acquire a better appreciation of the background of this invention, it should be understood that the crossbar is installed in the outlet of a plumbing fixture for example such as a lavatory, sink or the like in which a spider-like member is normally employed in the waste outlet .in order to serve as a means for catching solid objects which might normally tend to fall into the waste outlet or trap and make them .difiicult to recover under certain conditions. It should be understood that initially a waste outlet spud is normally used and in connection with the latter spud member, the crossbar is inserted somewhere conveniently along the length of the latter member so as to serve for the purpose intended and above described.

One of the objections to the previous constructions is that the crossbar member in most instances has been an integral part of the spud outlet so that in the event of damage or breakage in service, an entirely new spud member was necessary with the attendant expense. Then too, in many instances the crossbar member was made in a cast material and relatively easily broken and difiicult to replace.

Another important object therefore is to provide a crossbar member which is not only easily and simply replaced as well as initially installed but also one which is relatively cheap and which does not add substantially to the cost of the waste outlet spud.

Other objects and advantages will become more readily apparent in connection with th reading of the specification which follows in light of the accompanying drawing in which:

Fig. 1 is a preferred application of our invention.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a modified form of our invention.

Fig. 4 is a sectional view taken on the line 44 of Fig. 3.

Fig. 5 is an exterior view of a further modified form of crossbar.

Similar reference numerals apply to similar parts throughout the several views.

Referring now to Fig. 1, the spud outlet which is of the conventional type and designated generally l is provided with the usual upper flange portion ZWhlCh normally rests within the aperture of the enameled surface of the lavatory or sink outlet (not shown). The lower end portion of the spud l is preferably threaded as at 3, the latter threaded end portion being a running thread and is used with a nut (not shown) for the purpose of attaching the spud fixedly to the lavatory or sink.

Somewhere along its length preferably at a central portion thereof, the spud I is provided with the oppositely disposed openings 4 having a relieved portion at their lower portion 5 to interrupt the otherwise continuous annular wall 6.

Positioned within the extended lower apertured portion 5, the crossbar member 1 bearing the general configuration of a figure 8 as more clearly shown in Fig. 2 is snugly fitted by slightly springing it within the opposite apertured portions 5 and 5 as shown in the above mentioned figure. It should be apparent that by reason of its shape the crossbar member '1 is capable of slight distortion to permit it to be inserted snugly within the apertures 5 and be held in place by virtue of the inherent resilience of the shape of the article and the nature of the material of which it is made, which may be either metallic or nonmetallic. The crossbar in addition to being frictionally gripped is supported by the arcuate surfaces 8. Thus it should be clear that by a relatively simple means an effective crossbar has been provided with a quick method of replacement and attachment.

In a further modified form as shown in Figs. 3 and 4, the crossbar member 9 of substantially hour-glass configuration may be used with equal y good results since it possesses the desired amount of resilience to make a snug fit with the end surfaces in the portions 5 of the opening 4 as indicated. The end portions 11 and 12 of the crossbar 9 are snugly retained within the openings 5 as shown. It may be desirable in some cases to attach the resilient crossbar more positively to the spud l and this is done by means of the form shown in Fig. 5, in which the crossbar l3 has the extended arms 14 provided with the notches 15 for engagement with the end surfaces of the aperture 5. Thus it should be apparent that the particular form of the crossbar member in order to embody the desired resilience may assume a wide variety of shapes without necessarily being restricted to the figure 8 or hour-glass shapes illustrated herein.

It is therefore evident that a novel crossbar device for waste mechanisms or the like have been devised in which the numerous details of construction may be varied throughout a wide range without departing from the principles disclosed herein. It is therefore not proposed to limit the patent granted hereon otherwise than as necessitated by the appended claim interpreted in light of the prior art.

We claim:

In a waste mechanism comprising a hollow cylindrical portion with oppositely disposed cutaway portions, a crossbar member therefor of the character described comprising a wire-like material substantially of a figure 8 configuration with a space between opposite end portions there of to permit limited lengthwise resilience therebetween, the said configuration providing for the connecting diagonal portion of the figure 8 to be interposed between said end portions to provide a limited clearance on each side of said diagonal portion of the figure 8 to permit said 20 limited lengthwise resilience, the said crossbar being snugly fitted resiliently between said oppositely disposed cut-away portions to extend transversely across the said hollow cylindrical portion.
